Hoymiles launches 22kW V2X charger

Hoymiles on September 7 unveiled a 22-kW bidirectional DC charger aimed at tying electric vehicles more tightly into household energy systems. The Hangzhou-based company said the unit works with its HiOne all-in-one battery energy storage system, adding EV charging and discharge to a stack that already includes solar, storage, energy management and home backup.

Hoymiles said the charger is designed so solar panels, home batteries, EVs and the grid can operate as one system, with the car acting as an additional energy resource for the home. (hoymiles.com) ### What exactly did Hoymiles launch? The product is listed as the HiOne-22VD-G3, a V2X DC charger built for compatibility with the company’s HiOne residential battery platform. Hoymiles describes it as a bidirectional charger that allows energy to move between the vehicle and the home rather than only from the grid into the car. (prnewswire.com) The charger delivers up to 22 kW of DC bidirectional charging power, according to Hoymiles product materials. A company specification sheet says it supports a vehicle-side voltage range of 200-1000 volts DC, uses a CCS2 connector and carries an IP66 protection rating. (prnewswire.com) ### Why is the charger DC rather than AC? Hoymiles said the unit is DC-coupled, which means it can charge an EV directly from solar generation and battery storage without routing power through the vehicle’s onboard AC charger. In the company’s description, that setup reduces conversion steps compared with AC-coupled charging. (hoymiles.com) The company already sells AC EV chargers in 7 kW, 11 kW and 22 kW versions. Those products can connect to Hoymiles storage inverters, but the new unit is presented as the company’s V2X-capable option for bidirectional home-energy use.

Hoymiles said the charger supports vehicle-to-home and vehicle-to-grid operation, allowing an EV battery to supply household loads or interact with the wider grid when paired with the rest of the system. The company says that can let a car serve as backup power or as an additional storage asset inside the home-energy setup. The HiOne platform page markets that idea directly to homeowners. (prnewswire.com) Hoymiles says an EV connected through the V2X charger can become a home backup source and presents the charger as one module within a broader package that includes inverter and energy management functions, modular batteries, a gateway for whole-home backup and the S-Miles Cloud monitoring platform.

At that launch, the company said the product combined inverter, battery and energy management functions in a compact home-storage package targeted at Europe. (hoymiles.com) The September charger launch extends that platform rather than replacing it. Hoymiles’ current HiOne materials show the V2X charger as part of the same residential architecture, alongside modular battery units and backup hardware.

Hoymiles’ public materials reviewed on September 7 do not specify pricing, country-by-country availability or a launch timetable for individual markets. The company’s product pages and brochure identify the charger model and technical specifications, but they do not list a retail price. The next concrete step is product rollout through Hoymiles’ regional channels and supporting documentation. (hoymiles.com) As of September 7, the charger appears on Hoymiles product pages as HiOne-22VD-G3 and in the company’s downloadable DC charger specification sheet. (hoymiles.com 1) (hoymiles.com 2)
